If you have installed an Interim Fix for Websphere Application Server APAR PM44303, Websphere Application Server Fixpack 21 or Fixpack 23 which includes APAR PM44303 , you have the potential for an authenticated user on the network to bypass security restrictions, caused by an error when validating user credentials. This access requires a medium level of complexity. This could allow a user to gain unauthorized administrative access to an application and potentially gain access to confidential and critical customer data.

This could allow the user to modify the configuration of the TFIM server causing the server to work incorrectly. The user could also stop or uninstall the TFIM Admin console causing a denial of service for the TFIM clients. Lastly the user could modify the TFIM Administrator password allowing access to the TFIM Admin console and TFIM information.

1. Determine the WAS server version which is available on the Integrated Systems Console Welcome page. 2. If an affected version is present, apply the updated fix identified below or upgrade to WAS version 7.0.0.24 or higher as soon as possible
